I've learned that in order to have a successful career it's not necessary to go into higher education. Not having a degree does not make you dumb and, if you want, you can always continue your education later on in life. One thing I did not expect was to become more intelligent as I grew older. I mean as far as studying is concerned. There are things that I was not capable of grasping intellectually when I was in my teens, which I have been able to learn and understand much later in life. I did not develop the ability to do critical analysis until long after leaving high school and I was able to pass exams as an adult that I would not have been able to do when I was younger. What is the most unexpected thing that you have learned along the way?
